Current status of a TOF-Laue single crystal neutron diffractometer SENJU

A TOF-Laue single crystal neutron diffractometer at the BL18 of MLF/J-PARC, SENJU, was designed for precise crystal and magnetic structure analyses under extreme environments such as low-temperature, high-pressure and high-magnetic field. On-beam test measurements of 4K cryostat, high-pressure cell and vertical-field superconducting magnet were carried out to evaluate the background from each device. All devices worked as planned and single crystal neutron diffraction measurements under extreme conditions on SENJU were successfully achieved.
